[0043] figure 1 is a perspective view of the water faucet device 2 according to the first embodiment. The faucet assembly 2 is installed on a kitchen sink (not shown in the figure). exist figure 1 The part that is not visually identifiable, that is, the part located inside the kitchen sink, is omitted in . In addition to the kitchen, the faucet device 2 can also be installed in, for example, washrooms and bathrooms.

[0044] The faucet assembly 2 comprises a body part 4 , a lever handle 6 and a drain head 8 . The water faucet device 2 is a so-called single-lever type water faucet. The temperature of the discharged water can be adjusted by pivoting the lever handle 6 left and right. The amount of discharged water can be adjusted by pivoting the lever handle 6 up and down. A valve mechanism capable of adjusting the temperature and amount of discharged water is housed inside the body portion 4 . Such valve mechanisms are known.

Abstract

The object of the invention is to provide a water purification cartridge which is capable of preventing false recognition of a discharge of water and has excellent reliability. As a solution, a water discharge head 8 has: a restriction member RG1 which can be transitioned between a first state J1 and a second state J2, and which restricts switching from raw water to purified water by a switching mechanism in the first state, and permits switching from raw water to purified water by the switching mechanism in the second state; a water purification cartridge provided with a restriction release unit DR1 which transitions the restriction member RG1 from the first state J1 to the second state J2, and a water purification cartridge PC1 comprising a water-impermeable tip closed outer surface 196; and a water purification cartridge receiving part. The tip closed outer surface 196 faces a raw water flow passage WG. The restriction member RG1 is arranged in a purified water flow passage WJ.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201880086172.1 and the invention name "drain head with water purification function, water purification filter element and faucet device" filed on April 13, 2018. technical field [0002] The invention relates to a drain head with water purification function, a water purification filter element and a faucet device. Background technique [0003] A drain head is known which includes a water purification cartridge and has a water purification function. JP3454756B2 discloses a shower head that has a water purification function and can switch between a raw water flow path that does not pass through a water purification filter element and a purified water flow path that passes through a water purification filter element. [0004] This type of drain head or a faucet device equipped with the same includes an operating portion capable of switching between raw water disch...
